Description

DISPOSITIF EMBARQUE DE LAVAGE ET DE TRAITEMENT, NOTAMMENT POUR MACHINE A VENDANGER ON-BOARD WASHING AND TREATMENT DEVICE, PARTICULARLY FOR A HARVESTING MACHINE
La présente invention a pour objet un dispositif de lavage et éventuellement de traitement, notamment applicable aux machines à vendanger, un tel système étant du type embarqué.The present invention relates to a washing device and possibly treatment, in particular applicable to harvesting machines, such a system being of the on-board type.
Si l'on prend l'exemple des machines à vendanger de type connu, elles comprennent un châssis avec une motorisation, un circuit hydraulique et des roues sur trains enjambeurs ainsi qu'une cabine de pilotage et une tête de récolte qui comprend les moyens de secouage visant à faire tomber les grains, des moyens de récupération et de transfert de ces grains, des moyens de stockage de ces grains transférés. Ces machines agricoles sont particulières en ce sens qu'il s'agit de machines prévues pour circuler sur des terrains certaines fois boueux ou poussiéreux, qui récoltent des grains de raisin destinés à fermenter dont on souhaite la plus grande propreté au moment de la récolte et dont les conditions de travail génèrent des corps étrangers à la vendange, souvent de petites dimensions.If we take the example of harvesting machines of known type, they include a chassis with a motorization, a hydraulic circuit and wheels on straddle trains as well as a pilot cabin and a harvesting head which includes the means of shaking aimed at dropping the grains, means for recovering and transferring these grains, means for storing these transferred grains. These agricultural machines are particular in the sense that they are machines intended to circulate on land which is sometimes muddy or dusty, which harvest grapes intended for fermenting which is desired to be as clean as possible at the time of harvest and whose working conditions generate bodies foreign to the harvest, often of small dimensions.
En effet, le secouage ou le battage provoque la chute simultanée de feuilles et autres morceaux de sarments. Ces morceaux sont pour l'essentiel aspirés par les ventilateurs/broyeurs qui les réduisent à l'état de débris et rejetés. Or, la vendange avec les machines à vendanger provoque l'éclatement de grains de raisin, ce qui macule de sucre une grande partie de la machine et surtout la tête de récolte. Les débris rejetés et tous les autres corps étrangers projetés ont tendance à être retenus par cette pellicule de sucre qui agit comme une colle.In fact, shaking or threshing causes leaves and other pieces of shoots to fall simultaneously. These pieces are mainly sucked by the fans / shredders which reduce them to the state of debris and rejected. However, the harvest with the harvesting machines causes the bursting of grapes, which stains much of the sugar and especially the harvest head. The rejected debris and all the other foreign bodies projected tend to be retained by this film of sugar which acts like a glue.
Le châssis lui-même, comme celui de toutes les machines agricoles est bien souvent le lieu de rétention de grosses quantités de boue. Les utilisateurs se trouvent dans l'obligation de nettoyer la machine une, voire deux fois par jour ou plus si la machine travaille jour et nuit.The chassis itself, like that of all agricultural machinery, is often the place of retention of large amounts of mud. Users are obliged to clean the machine once or twice a day or more if the machine works day and night.
Cette obligation résulte aussi du fait qu'il est quasiment impossible d'intervenir mécaniquement sur la machine si celle-ci colle sur toute sa surface, ne serait ce que pour vérifier le bon état des organes. L'accumulation de plusieurs couches de sucre, surtout si la machine a des périodes d'interruption, peut provoquer le dysfonctionnement de certains éléments, une usure prématurée de certaines parties mobiles délicates.This obligation also results from the fact that it is almost impossible to mechanically intervene on the machine if it sticks over its entire surface, if only to check the good condition of the organs. The accumulation of several layers of sugar, especially if the machine has periods of interruption, can cause the malfunction of certain elements, premature wear of certain delicate moving parts.
Organoleptiquement et sanitairement parlant, il paraît difficile de laisser certaines accumulations de raisins pourrissant en des recoins du circuit de la vendange dans la machine à vendanger.Organoleptically and in terms of health, it seems difficult to leave certain accumulations of rotting grapes in corners of the harvest circuit in the harvesting machine.
De façon générale, l'entretien et le nettoyage de telles machines sophistiquées s'avèrent nécessaire, car certaines parties mobiles dans la tête de récolte sont en effet délicates et travaillent à des fréquences assez élevées. Le sucre ne doit pas entraver le fonctionnement de certains organes comme les moyens de secouage ou de battage qui sont nécessairement articulés, ou comme les convoyeurs qui comportent des chaînes, des tapis convoyeurs, des écailles ou godets articulés, ou encore comme les carters, les voiles en plastique de protection.In general, the maintenance and cleaning of such sophisticated machines is necessary, because certain moving parts in the harvesting head are indeed delicate and work at fairly high frequencies. The sugar must not hamper the functioning of certain organs such as the shaking or threshing means which are necessarily articulated, or like the conveyors which comprise chains, conveyor belts, articulated scales or buckets, or even like the casings, the protective plastic sails.
On sait aussi que, dans l'agriculture et plus particulièrement dans le domaine viticole, il existe des entrepreneurs qui possèdent un parc machine, notamment des machines à vendanger, et dont le métier consiste à proposer comme prestation la vendange d'une propriété à l'aide de telles machines.We also know that, in agriculture and more particularly in the wine sector, there are entrepreneurs who own a machine park, in particular harvesting machines, and whose job is to offer as a service the harvest of a property to the owner. using such machines.
Un tel prestataire ne peut pas se présenter auprès d'un nouveau client avec une machine couverte de sucre et de débris de la précédente prestation. Ceci conduit donc aussi à des lavages réguliers.Such a service provider cannot come to a new customer with a machine covered with sugar and debris from the previous service. This therefore also leads to regular washes.
On se heurte alors à plusieurs problèmes détaillés, ci-après sans respecter nécessairement un classement par degré d'importance. Le premier est dû au fait que la machine comprend des recoins difficiles d'accès, qui obligent l'opérateur à monter sur la machine et à la parcourir.We then come up against several detailed problems, below without necessarily respecting a classification by degree of importance. The first is due to the fact that the machine includes recesses which are difficult to access, which oblige the operator to climb onto and traverse the machine.
Un autre phénomène résulte du fait que de nombreux points fragiles, comprenant des joints et autres soufflets ou bavettes interdisent l'emploi de nettoyeurs à haute pression à 1 00 bars et plus.Another phenomenon results from the fact that many fragile points, including gaskets and other bellows or flaps prevent the use of high pressure cleaners at 1,00 bars and above.
Qui plus est, ce type de nettoyeur a plutôt tendance à déplacer la saleté car si la puissance mécanique permet sans nui doute le décollage des particules et débris et la remise en solution du sucre, le volume d'eau projeté est très faible et n'assure pas un nettoyage global suffisant. Ces opérations de nettoyage posent aussi la contrainte du temps car ces machines doivent être rentabilisées sur des périodes très courtes et les durées de fonctionnement doivent être aussi longues que possible, en limitant les arrêts pour l'entretien. H est assez incongru de perdre du temps pour du lavage. On sait, par ailleurs, que le graissage des articulations et d'autres parties tournantes ou mobiles est généralement assuré par une centrale embarquée, avec un déclenchement séquentiel entièrement automatisé, qui injecte au droit des points à graisser une quantité donnée de matière lubrifiante. Ce mode de lubrification automatique est de plus en plus monté sur ces machines. D'autres contraintes sont aussi à prendre en considération comme la présence de prises de courant et d'eau simultanément sur une zone potentielle de lavage, ou la pression et le débit d'alimentation du point d'eau qui peuvent varier d'un lieu à l'autre.What is more, this type of cleaner tends to displace dirt because if the mechanical power undoubtedly allows the removal of particles and debris and the re-solution of sugar, the volume of water sprayed is very low and doesn’t not provide sufficient overall cleaning. These cleaning operations also pose the time constraint because these machines must be profitable over very short periods and the operating times must be as long as possible, limiting downtime for maintenance. It is pretty incongruous to waste time washing. We know, moreover, that the lubrication of joints and other rotating or mobile parts is generally ensured by an on-board control unit, with a fully automated sequential triggering, which injects right to the points to be lubricated with a given quantity of lubricating material. This automatic lubrication mode is more and more installed on these machines. Other constraints are also to be taken into account such as the presence of electrical outlets and water simultaneously on a potential washing area, or the pressure and the flow rate of the water point which can vary from place to place. to the other.
Il faut actuellement entre 3 et 5 m3 d'eau lorsqu'un opérateur souhaite nettoyer une machine à vendanger, pour donner un ordre d'idée.Currently between 3 and 5 m 3 of water is required when an operator wishes to clean a harvesting machine, to give an idea.
Le temps nécessaire est aisément déduit du débit de sortie du moyen de lavage et de la quantité d'eau précitée de plusieurs m3.The time required is easily deducted from the outlet flow rate of the washing means and from the abovementioned quantity of water by several m 3 .
Même à des débits de 1 00 litres par minute, on arrive vite à des durées de plusieurs dizaines de minutes. Aussi, la présente invention consiste à proposer un circuit embarqué sur la machine, entièrement autonome, nécessitant uniquement une bâche contenant le volume d'eau nécessaire ou un poste d'alimentation à gros débit, c'est-à-dire une petite section et une forte pression ou une forte section et une faible pression ou encore une forte section et une forte pression.Even at flow rates of 1,00 liters per minute, we quickly arrive at times of several tens of minutes. Also, the present invention consists in proposing an on-board circuit on the machine, entirely autonomous, requiring only a tarpaulin containing the necessary volume of water or a high flow supply station, that is to say a small section and a high pressure or a high section and a low pressure or else a high section and a high pressure.
Ce circuit permet un nettoyage très rapide en préservant les éléments fragiles et en assurant une action sur certains points précis. Le fonctionnement peut-être entièrement automatisé et programmé avec des durées de cycle très courtes.This circuit allows a very fast cleaning by preserving the fragile elements and by ensuring an action on certain precise points. The operation can be fully automated and programmed with very short cycle times.
Le circuit peut-être coordonné dans ses actions avec les cycles de graissage.The circuit can be coordinated in its actions with the lubrication cycles.
On entend pour la suite de la description, par "rinçage" les différentes phases de prélavage, lavage et rinçage final proprement dit.For the remainder of the description, the term "rinsing" means the various phases of prewash, washing and final rinsing proper.
A cet effet, l'invention concerne un dispositif de lavage embarqué, notamment pour l'élimination du sucre et de la pulpe accumulés sur une machine à vendanger, du type comprenant un châssis motorisé sur roues et une tête de récolte, généralement amovible, caractérisé en ce qu'il comprend des moyens d'alimentation en eau, au moins un premier et un second circuits, le premier circuit dit de rinçage comprenant une canalisation avec des buses d'aspersion à faible pression de sortie et gros débit et le second circuit dit de décollage comprenant une canalisation avec des buses de décollage à plus faible débit et plus forte pression. Plus particulièrement, les buses de rinçage sont situées en partie haute de la machine et comprennent des moyens brise-jet interposés sur le jet de sortie en sorte de provoquer une aspersion et en ce que la canalisation sur laquelle sont piquées lesdites buses de rinçage est à gros débit.To this end, the invention relates to an on-board washing device, in particular for removing the sugar and pulp accumulated on a harvesting machine, of the type comprising a motorized chassis on wheels and a harvesting head, generally removable, characterized in that it comprises water supply means, at least a first and a second circuit, the first so-called rinsing circuit comprising a pipe with spray nozzles with low outlet pressure and high flow rate and the second circuit said takeoff comprising a pipe with takeoff nozzles at lower flow rate and higher pressure. More particularly, the rinsing nozzles are located in the upper part of the machine and comprise jet-breaking means interposed on the outlet jet so as to cause spraying and in that the pipe on which said rinsing nozzles are stitched is high flow.
Les buses de décollage sont quant à elles orientées vers des points difficilement accessibles de la machine et sujets à accumulation, quelle que soit la hauteur de la machine à laquelle elles sont positionnées, la canalisation sur laquelle sont piquées lesdites buses de décollage étant à petit débit.The take-off nozzles are oriented towards points which are difficult to access from the machine and subject to accumulation, whatever the height of the machine on which they are positioned, the pipe on which said take-off nozzles are stitched at low flow. .
Selon une autre caractéristique, les moyens d'alimentation en eau comprennent une pompe à gros débit, embarquée et des moyens de raccordement à un point d'eau et de plus, en option, un flexible équipé d'une crépine en sorte de pouvoir pomper de l'eau directement d'une bâche. Il est de plus prévu un circuit annexe pour le lavage du châssis Le dispositif est équipé, dans ce mode de réalisation sophistiqué, d'un programmateur de commande des différents cycles et des différents circuits, pour faciliter le travail de l'opérateur.According to another characteristic, the water supply means comprise a high flow pump, on board and means for connection to a water point and in addition, optionally, a hose fitted with a strainer so as to be able to pump water directly from a tarpaulin. There is also an additional circuit for washing the chassis The device is equipped, in this sophisticated embodiment, with a programmer for controlling the different cycles and the different circuits, to facilitate the work of the operator.
Selon un perfectionnement, le dispositif comprend des moyens d'injection de produits de traitement, notamment des produits bactéricides et/ou fongicides, dans l'eau d'alimentation.According to an improvement, the device comprises means for injecting treatment products, in particular bactericidal and / or fungicidal products, into the feed water.
Sur les dessins annexés, on a représenté sur les différentes figures un mode de réalisation particulier et préférentiel, non limitatif.In the accompanying drawings, there is shown in the various figures a particular and preferred embodiment, not limiting.
- la figure 1 représente une vue schématique en perspective d'une machine à vendanger,FIG. 1 represents a schematic perspective view of a harvesting machine,
- la figure 2 représente un circuit type pouvant être embarqué, etFIG. 2 represents a typical circuit that can be carried, and
- la figure 3 représente une vue d'un mode de réalisation d'une buse d'aspersion telle qu'utilisée.- Figure 3 shows a view of an embodiment of a spray nozzle as used.
Sur la figure 1 , on a représenté une machine à vendanger comprenant un châssis 10 monté sur roues 1 2, toutes motrices grâce à des moteurs hydrauliques généralement, et une tête de récolte 1 4 dont on peut voir les moyens de secouage ou de battage 1 6.In Figure 1, there is shown a harvesting machine comprising a chassis 10 mounted on wheels 1 2, all driven by hydraulic motors generally, and a harvesting head 1 4 which can be seen the shaking or threshing means 1 6.
Cette machine comprend, outre une cabine de conduite 1 8 optionnelle, un moteur avec son circuit hydraulique associé 20, des moyens de transfert 22, ainsi que des moyens de stockage temporaire 24 des grains de raisin, équipés de moyens de répartition 26 dans ces moyens de stockage, en l'occurrence une vis d'Archimède 28.This machine comprises, in addition to an optional driver's cab 1 8, a motor with its associated hydraulic circuit 20, transfer means 22, as well as temporary storage means 24 of the grapes, equipped with distribution means 26 in these means storage, in this case an Archimedes screw 28.
Le but est de nettoyer une telle machine et surtout l'ensemble des éléments en contact avec le raisin. II faut remettre en solution le sucre, décoller la pulpe et les débris, et évacuer toutes ces impuretés.The goal is to clean such a machine and especially all the elements in contact with the grapes. It is necessary to re-dissolve the sugar, to peel the pulp and the debris, and to evacuate all these impurities.
Tout d'abord, comme indiqué sur la figure 2, le dispositif selon l'invention comprend un flexible 32 muni à son extrémité d'une crépine 34. Ce flexible comporte aussi un raccord 36 susceptible d'être connecté à une prise d'eau sous pression du réseau.First of all, as indicated in FIG. 2, the device according to the invention comprises a hose 32 provided at its end with a strainer 34. This hose also comprises a connector 36 capable of being connected to a water intake under network pressure.
Une pompe 38 permet d'injecter de l'eau avec une pression donnée dans le circuit 40 du dispositif de lavage selon l'invention. Ce circuit 40 comprend un premier circuit 42 de rinçage dont l'ouverture est commandée par une vanne 44 en l'occurrence une électrovanne et un second circuit 46 de décollage des débris dont l'ouverture est commandée par une vanne 48, également une électrovanne dans ce mode de réalisation. Le premier circuit 42 de rinçage comprend des buses d'aspersion 50 connectées sur une canalisation 52 de diamètre suffisant pour conférer un gros débit. Ces buses sont disposées en partie haute de la tête de récolte en sorte que les écoulements et les aspersions couvrent toute les surfaces intérieures et extérieures. Par contre, ces buses 50 ont des caractéristiques particulières et un mode de réalisation est représenté sur la figure 3.A pump 38 makes it possible to inject water with a given pressure in the circuit 40 of the washing device according to the invention. This circuit 40 comprises a first rinsing circuit 42 whose opening is controlled by a valve 44 in this case a solenoid valve and a second debris take-off circuit 46 whose opening is controlled by a valve 48, also a solenoid valve in this embodiment. The first rinsing circuit 42 comprises spray nozzles 50 connected to a pipe 52 of sufficient diameter to give a large flow. These nozzles are arranged in the upper part of the harvesting head so that the spills and sprinkles cover all the interior and exterior surfaces. On the other hand, these nozzles 50 have particular characteristics and an embodiment is shown in FIG. 3.
Une telle buse a un orifice de forte section 54 et génère un jet 56 de gros débit, à la pression du circuit 42, donc à la pression de la pompe 38. Ce jet 56 est cassé par un brise-jet 58, en l'occurrence un cône 60 et un disque de répartition, si bien que le débit est important avec une pression d'adduction importante mais uniquement avec une pression gravitaire lors de l'impact sur les éléments de la machine.Such a nozzle has a large section orifice 54 and generates a jet 56 of high flow rate, at the pressure of the circuit 42, therefore at the pressure of the pump 38. This jet 56 is broken by a jet breaker 58, in the occurrence a cone 60 and a distribution disc, so that the flow is important with a significant supply pressure but only with a gravity pressure upon impact on the elements of the machine.
Le second circuit 46 comprend des buses 62 de décollage prévues pour être disposées au droit des endroits difficilement accessibles ou au droit des lieux préférentiels d'accumulation.The second circuit 46 includes take-off nozzles 62 designed to be placed at the level of places that are difficult to access or at the level of preferential places of accumulation.
Le jet de ces buses 62 de décollage a un impact beaucoup plus ciblé. Ces buses de décollage peuvent être réparties sur toute la hauteur de la machine.The jet of these take-off nozzles 62 has a much more targeted impact. These take-off nozzles can be distributed over the entire height of the machine.
En effet, leur rôle est uniquement de décoller et de nettoyer une zone localisée puis de les déplacer vers un endroit plus accessible mais c'est l'eau du circuit primaire à gros débit qui entraîne les débris ainsi décollés du haut de la machine vers le bas, évitant toute nouvelle salissure.In fact, their role is only to take off and clean a localized area and then move them to a more accessible place, but it is the water from the high-flow primary circuit that drives the debris thus lifted from the top of the machine to the low, avoiding any new soiling.
Les séquences de lavage peuvent être programmées grâce à un programmateur 64 qui commande les électrovannes, la mise en service de la pompe. Un tel programmateur peut aussi être relié au système de graissage automatique lorsqu'il y en a un en sorte de déclencher une séquence de graissage spécifique après le lavage et avant remise en service.The washing sequences can be programmed using a programmer 64 which controls the solenoid valves, the commissioning of the pump. Such a programmer can also be connected to the automatic lubrication system when there is one so as to trigger a specific lubrication sequence after washing and before returning to service.
On comprend ainsi qu'avec une forte pression et un gros débit dans la canalisation des premier et second circuits, l'opération de lavage dure peu de temps car le gros volume d'eau de plusieurs m est rapidement consommé et judicieusement réparti sans provoquer de quelconques dégradations.It is thus understood that with a high pressure and a large flow in the pipeline of the first and second circuits, the washing operation lasts a short time because the large volume of water of several m is quickly consumed and judiciously distributed without causing any degradations.
On peut aussi prévoir un circuit annexe non représenté mais du type de celui proposé sur la figure 2, ce circuit ayant pour objet le lavage des organes annexes, roues, châssis, vitres, moteur.One can also provide an annex circuit not shown but of the type of that proposed in FIG. 2, this circuit having for its object the washing of the annex organs, wheels, chassis, windows, engine.
Un tel circuit n'est mis en service que de façon optionnelle lorsque les conditions de travail le rende nécessaire, boue, poussière par exemple.Such a circuit is only put into service optionally when the working conditions make it necessary, mud, dust for example.
Un tel circuit comprendra également deux circuits, un premier de rinçage et un second de décollage. On peut ainsi réduire la quantité d'eau consommée si seule la tête de récolte est à nettoyer sans que l'extérieur soit particulièrement sale.Such a circuit will also include two circuits, a first rinse and a second takeoff. It is thus possible to reduce the amount of water consumed if only the harvesting head is to be cleaned without the outside being particularly dirty.
La pompe est avantageusement entraînée mécaniquement à partir du moteur ou par l'hydraulique de la machine si bien que celle-ci est parfaitement autonome. Un autre avantage non négligeable du dispositif selon l'invention est celui de pouvoir injecter dans le circuit un agent de traitement liquide, fongicide ou bactéricide durant un lavage donné, les contraintes normatives d'hygiène devenant de plus en plus draconiennes.The pump is advantageously driven mechanically from the motor or by the hydraulics of the machine so that the latter is perfectly autonomous. Another non-negligible advantage of the device according to the invention is that of being able to inject into the circuit a liquid, fungicidal or bactericidal treatment agent during a given washing, the normative hygiene constraints becoming more and more draconian.
Comme le circuit est embarqué, il suffit de prévoir un piquage avec une prise Venturi calibrée qui permet de doser et d'aspirer la quantité voulue de produit en fonction du débit d'eau.As the circuit is on-board, it suffices to provide a tapping with a calibrated Venturi plug which allows the required quantity of product to be dosed and aspirated according to the water flow rate.
L'installation des différentes buses tant en nombre qu'en positionnement dépend des modèles de machines et de leurs agencements spécifiques, le tracé du circuit étant à la portée de l'homme de l'art. The installation of the different nozzles both in number and in positioning depends on the models of machines and their specific arrangements, the layout of the circuit being within the reach of those skilled in the art.
